Abstract
The utility model relates to an automobile damper for internally controlling the oil leakage, which comprises a damper cylinder body, a guide holder, a piston rod and a piston, wherein the guide holder is internally provided with a sliding bearing matched with the piston rod, a ring-shaped working cavity is formed between the axial directions of the guide holder and the sliding bearing, and the ring-shaped working cavity is internally provided with an oil retainer. During the process of resetting movement of the damper of the utility model, the oil retainer can effectively control the oil flow quantity in the ring-shaped gap formed by matching the sliding bearing and the piston rod, can control the oil pressure of an oil seal during the driving with the height (> 0.3m/s), prolongs the service life of the damper, can control the flowing oil in the gas during the driving with the height (less than or equal to 0.1 m/s), reduces the percentage of the flowing quantity of the leaked oil and the normal flowing quantity of the oil of a valve throttle, and improves the stability of the damping force of the damper with low speed.
Description
Technical field
The utility model relates to vehicle shock absorber internal control oil liquid leakage structure.
Background technique
In automotive suspension, the main effect of vibration damper is to-and-fro motion damping force decay body vibrations that produces and the vibration that suppresses wheel by vibration damper.The decay body vibrations, it is more comfortable that the people is taken.Improve ride of vehicle, suppress the vibration of wheel, the ground connection property of tire when strengthening automobile running provides the stability of vehicle driving.Mating by the vehicle suspension system requirement of vibration damper in this external characteristics.All the time the damping force that produces under various speed in the design of vibration damper and in making is come requirement as the important indicator of mating with bearing spring.The damping force that each velocity shooting produces when that is to say vibration damper work must reach the tolerance range of drawing design.When designing, vibration damper how to control the concern that internal leakage under the lower-speed state all is subjected to the artificer all the time.Because there is certain clearance in the cooperation of component, therefore just inevitably there is internal leakage.Particularly vibration damper is at 0.05m/s, and the adjustment of damping force mainly guarantees by the size of adjusting throttle valve plate opening in the valve system under the 0.1m/s low speed.But the fluid of this opening circulation volume is often very little.If at this moment the slit that forms in piston rod and sliding bearing assembling back is bigger, it is opening when passing through the bigger and ratio value dispersion of the flow proportional of fluid that the volume that at this moment leaks oil from the slit accounts for from valve, will cause the unstability of damping force value.
The model utility content
In order to solve the internal leakage problem that existing vehicle shock absorber exists, the utility model provides a kind of vehicle shock absorber of realizing the internal control oil liquid leakage.
The vehicle shock absorber of realizing the internal control oil liquid leakage comprises vibration damper cylinder body, guide holder, piston rod and piston, is provided with the sliding bearing that cooperates with piston rod in the guide holder.Be provided with an annular working chamber at guide holder and sliding bearing between axially, in annular working chamber, be provided with flinger ring.
After being blocked by flinger ring, the fluid of the annulus internal leakage that sliding bearing and piston rod form when vibration damper is worked guaranteed from the stability of the logical oil of restriction.Damping force under the vibration damper low speed will be gone to realize, facilitated the stability that changes damping force under the speed by the power value of preset.
Useful technique effect of the present utility model embodies in the following areas:
1, vibration damper is in the to-and-fro motion process, and flinger ring can effectively be controlled sliding bearing and cooperate fluid amount of flow in the formed annulus with piston rod;
2, vibration damper the height (＞0.3m/s) travel in control oil sealing oil pressure, the prolongation vibration damper working life;
3, vibration damper low speed (≤0.1m/s) travel, make the fluid that flows in the slit controlled, reduced and leaked the amount of flow of fluid and the percentage of the normal fluid amount of flow of valve set section head piece, improved the stability of absorber damping force low speed.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1 and Fig. 2, realize that the vehicle shock absorber of internal control oil liquid leakage comprises vibration damper cylinder body, guide holder 1, piston rod 3 and piston 5, the sliding bearing 2 that cooperates with piston rod is installed in the guide holder 1, on the piston rod of piston one side piston valve block 4 is housed.Be provided with an annular working chamber at guide holder 1 and sliding bearing 2 between axially, flinger ring 6 is installed in annular working chamber.
During the vibration damper assembling, piston rod 3 passes in the hole, and flinger ring 6 keeps off back the fluid that flows in the slit in the clutch release slave cylinder.The internal diameter of flinger ring 6 and piston rod form certain matching relationship, can effectively control the amount of flow of fluid.
